Clalml.

The invention relates to windows and the like of the type having aplurality of pivoted louvers which may be opened for ventilation, saidlouvers being preferably of S-shape in trans- 5 verse section to excluderain, to direct incoming air upwardly into the room, and to downwardlydirect the outgoing air.

The principal object of the invention is to provide a simple andinexpensive, yet an efficient and desirable construction which permitseasy and rapid opening and closing of the louvers and permits any whichmay become damaged to be easily replaced with a new one.

With the foregoing and minor objects in view, the invention resides inthe novel subject matter hereinafter described and claimed, descriptionbeing accomplished by reference tothe accompanying drawings.

Fig. 1 is an inner side elevation with the louvers closed.

Fig. 2 is a vertical section on line 2-2 of Fig. 1.

Fig. 3 is a detail vertical section on line 3--3 of Fig. 1.

Fig. 4 is a fragmentary view similar to Fig. 1 but showing the louversopen.

Fig. 5 is a vertical section on line 5-5 of Fig. 4.

Fig. 6 is a vertical section online 6-6 of Fig. 4.

Fig. 7 is a disassembled fragmentary perspective view of one of. thelouvers and its mounting means.

Figs. 8 and 9 are detail vertical sections through the upper and lowerxed louvers and their mounting means.

Fig. l0 is a detail horizontal section on line I-I of Fig. 6.

While only one form of construction has been illustrated and will bespecically described, it is to be understood that numerous variationsmay be made within the scope of the invention as claimed.

A frame I0 is provided, formed from wood or metal as desired, said framehaving hollow stiles II, a hollow lower end member I2, and a hollowupper end member I3. The inner side wall Il of each stile II is providedwith a plurality of vertically spaced bearings I5 in which the pintlesI6 of the pivotally mounted louvers I1 are rockably mounted. Secured bypins I8l or otherwise secured to the outer ends of the pintles I6, areC-shaped crank arms I8 disposed within the hollow stiles I I, one end ofeach crank arm being connected with the adjacent pintle. The other endsof the various crank arms I8 are pivoted at I8 to inclined links 20,andthe lower ends of these links are-pivoted at 2I to vertical bars 22vwhich are slidably mounted within the stiles II. The lower ends of thebars 22 are operatively connected by means of. pivoted links 23 to ahorizontal rod 24 located within the hollow lower 5 end member I2 of theframe III. Suitable springs 25 are anchored in this end member and areconnected with the rod 2l to pull downwardly upon the latter, thusmoving the links 23 and the bars 22 downwardly and causing the latter to10 so pull upon the links 20 and crank arms I8 as to swing the louversI1 toward open position. The crank arms I8, links 20 and bars 22 are sorelated that when the louvers occupy fully open positions (Figs. 4, 5and 6), the convex edges of 16 said crank arms I8 will abut said bars22, limiting the louver movement.

A transverse operating shaft 26 extends into the lower end member I2under the rod 24 and is mounted in suitable bearings Il."l and I2", said,o shaft being provided with a hand crank or the like 21 by means ofwhich it may be turned.l This shaft 26 carries two arms 28 which arefixed thereon, and a peripherally grooved roller 29 is mounted betweensaid arms in engagement with 35 the lower side of the rod 24. By turningthe crank or the like 21 in the proper direction, the roller 29 forcesupwardly upon the rod 2|, thereby effecting closing of the louvers I1.When the roller is moved slightly past a dead-center posin tion,itobviously will lock the rod 24 raised, and the louvers closed. Tolimit movement of the roller to such a. position, the shaft 26 may wellbe provided with a stop arm 30 to strike one of the springs 25 or thebottom of the end memg5 ber I2.

Each louver I1 may be of glass or other transparent or translucentmaterial, of wood, metal or other preferred material. The ends of eachlouver are clamped between metal clamping 40 strips 3| and 32 by meansof bolts 33 passing through said strips and louver. To attach the louverto the pintles I6, each of these pintles is preferably soldered, brazed,welded or otherwise made integral with the strip II, and one of the ubolts 33 may well pass through the inner portion of said pintle, asshown. By connecting the louvers and pintles in this or an equivalentmanner, it will be readily seen that any damaged o louver may be quicklyand easily removed and replaced with another.

'Iwo iixed louvers Il are provided to coact with the endmost of thepivoted louvers I'I, said louvers I8 being secured to brackets 8l bybolts or the u like l0. These brackets are preferably provided withportions ll passing through slots 42 in the opposed walls of the endmembers I2 and I3, said portions 4I having angular ends Il within saidend members and secured thereto by screws or the like Il.

By providing the novel construction shown and described, or asubstantial equivalent thereof, it will be seen that the objects of theinvention may be expeditiously attained.

I claim:

1. A window comprising a frame having hollow stiles and a hollow lowerend member in communication with said stiles, louvers extending betweensaid hollow stiles and having pintles extending into the same, saidhollow stiles having inner walls through which said pintles extendrotatably, two vertical bars disposed in said holi low stilesrespectively, means in said hollow stiles operatively connecting saidbars with said pintles to operate said louvers when said bars are movedvertically, a horizontal rod within said lower end member and soconnected at its ends with the lower ends of said vertical bars thatsaid bars and rod are vertically movable in unison, and means extendinginto said hollow lower end member and operatively associated with saidrod to raise and lower the latter and said bars to operate said louvers.

2. A window comprising a frame, louvers extending between the framestiles and having pintles supported thereby, two vertical bars extendinglongitudinally oi.' said stiles, means operatively connecting said barswith said pintles to operate said louvers when said bars are movedvertically, a horizontal rod at the lower end of said frame andoperatively connected at its ends with the lower ends of said verticalbars for moving the latter vertically when said rod is moved vertically,spring means connected with said rod for vertically moving the latterand said bars in one direction, a manually operable rock shaft having acrank arm near said rod, and a roller on said crank arm engaging saidrod for vertically moving the latter and said bars in the otherdirection.

3. In a window or the like having a plurality of louvers provided withpintles, and bearings in which said pintles are mounted; C-shaped crankarms secured at one end to said pintles, links pivoted to the other endsof said C-shaped crank arms, and an operating bar pivoted to said linksand mounted for longitudinal movement, said bar being so related withsaid C-shaped crank arms and links as to strike the convex edges of saidC-shaped crank arms when the louvers occupy one extreme position.

4. A window comprising a frame, louvers eX- tending between the framestiles and having pintles supported thereby, two vertical bars extendinglongitudinally of said stiles, means opera.- tively connecting said barswith said pintles to operate said louvers when said bars are movedvertically, a horizontal rod at the lower end of said frame and soconnected at its ends with the lower ends of said vertical bars thatsaid bars and rod are vertically movable in unison, and meansoperatively associated with said rod for moving the latter and said barsvertically.

5. A window comprising a frame, louvers extending between the framestiles and having pintles supported thereby, two vertical bars extendinglongitudinally of said stiles, means operatively connecting said barswith said pintles to operate said louvers when said bars are movedvertically, a horizontal rod at the lower end of said frame andoperatively connected at its ends with the lower ends of said verticalbars for moving the latter vertically when said rod is moved vertically,a support under said rod and xedly carried by the frame, two elongatedspring arms secured upon said support and inclined upwardly towardopposite ends of said rod, the outer ends of said spring arms havingupstanding portions through which said rod passes to mount the latterfor vertical movement, and means for vertically moving said rod againstthe action of said springs.
